If you have a subwoofer that illuminates - there will be an extra set of terminals on the basket.

This requires a seperate set of power and ground wires along with a toggle switch.

If you want to - you can put the ground on the amplifier's ground, power off the amplifier's power (to a spdt relay) and have the relay activated with the remote wire terminal on the amplifier.
This way it will turn on and off with your stereo system and you wont come out in the morning to a drained battery from forgetting to turn it off.
